[Elecraft] normal K3 voltage drop on TX

[Jerry Moore]

Fair enough Tom :) , 
I've not had the pleasure of doing microwave other than
fixing/troubleshooting radar (APS 180/APS 80). My Navy training didn't
include soldering/crimping for radar other than cannon/other connections.
It's been a long time and I don't recall the magnetron connection types as
we generally would only replace crystals or the whole unit if there was an
issue. I did get to change a waveguide and test it with a sweep cart once.
That was a lot of fun.

You should be sure to NEVER say that around a microwave person! As long as
you stay in HF, crimps may be OK. As a retired microwave circuit and systems
design engineer, there will never be a crimped anything in my ham station.
Saying 'crimped' is better than soldered is the same as saying you don't
know what you are talking about! Just my opinion of course.

I respectfully disagree. A properly made crimp is superior to a soldered
connection. The key word being properly made. If you don't have the correct
tools to do a proper crimp then a good compromise is to solder the
connection after crimping, however, that's only to comply with connection
best practice to establish a good mechanical and electrical connection. A
proper crimp serves to mechanically weld the conductors together.
